Over 40000 visits to the open-ZB web site and 2000 downloads of the IEEE 802.15.4/ZigBee toolset. THANK YOU ALL FOR BEING PART OF THIS SUCCESS.

Manish Batsa (maba@isep.ipp.pt) has joined the ART-WiSe team! Manish is a distinguished Indian undergraduate student (4th year, Computer Science and Engineering IIT Roorkee) that is doing an internship at IPP-HURRAY (until the end of July). He will work in the context of the ongoing project with SSSUP (Pisa) and will focus his work on developing the missing functionalities of our IEEE 802.15.4/ZigBee protocol stack over ERIKA.

The President of the Portuguese Republic, Prof. Aníbal Cavaco Silva, visited the CISTER Research Unit at ISEP. Among other cutting-edge research highlights, there was a focus on the new paradigms of large-scale distributed embedded systems for monitoring critical physical infrastructures (e.g. electrical, water, oil distribution networks, bridges, highways, tunnels). The ART-WiSe and open-ZB research frameworks were shortly overviewed, stressing on our belief that using standard communication protocols (as ZigBee) and commercial off-the-shelf technologies can speed-up a wider utilization of these wireless sensor network infrastructures. The Minister of Science and Technology, Prof. José Mariano Gago was also present, among other distinguished visitors.

Ricardo Severino went to the RETIS Lab, Scuola Superiore Sant'Anna (http://retis.sssup.it) to foster the migration of the open-ZB IEEE 802.15.4/ZigBee protocol stack (http://www.open-ZB.net) to the ERIKA (http://erika.sssup.it) real-time operating system. Mission ends on the 9/MAY.

35000 visits :) After 17 months have elapsed since its release, the open-ZB web site already witnessed over 35000 visits. The total number of downloads so far is roughly 2000. The average daily rates are around 70 visits and 4 downloads Thank you ALL for being part of this success :)

Mangesh Chitnis, from the RETIS Lab, Scuola Superiore Sant'Anna (http://retis.sssup.it) came to Porto for the collaborative work on the migration of the open-ZB IEEE 802.15.4/ZigBee protocol stack (http://www.open-ZB.net) to the ERIKA (http://erika.sssup.it) real-time operating system. He gave a talk on the 30/APR/2008 oultining the most important features of the ERIKA real-time operating system.

Release of a Technical Report (HURRAY-TR-080401) on how to achieve "Real-Time Communications over Cluster-Tree Sensor Networks with Mobile Sink Behaviour". This proposes analytical models and describes a MATLAB tool for the worst-case dimensioning of cluster-tree ZigBee networks. Additionally, it demonstrates the validity and analyses the accuracy of our methodology through an experimental test-bed based on COTS ZigBee technology.

André Cunha spent one month in the RETIS Lab, Scuola Superiore Sant'Anna (SSSUP, Pisa, Italy), to start the migration of the open-ZB protocol stack to the ERIKA real-time operating system, together with researchers from the RETIS Lab. Mission ended 16/MAR/2008.

Paolo Pagano, Mangesh Chitnis and Antonio Romano, from the RETIS Lab (http://retis.sssup.it), Scuola Superiore Sant'Anna (http://www.sssup.it), came to Porto from 28-31/JAN/2008, for a workshop on wireless sensor networks (WSNs), namely to explore joint research on real-time communications in WSNs, based COTS communication protocols and operating systems.

Release of a Beta Version of the IEEE 802.15.4 implementation for TinyOS v2.0.

A stable release will be available shortly, including the Time Division Beacon Scheduling and the ZigBee Network Layer

First anniversary of the Open-ZB web site!!!

One year has elapsed since the release of the Open-ZB web site. During this period, we witnessed over 18000 visits and over 700 downloads, from worldwide reputed universities, RTD institutions and companies. Within this context, several bi-lateral and multi-lateral collaboration initiatives have been triggered, which we believe will leverage even further the quality, completeness and usage of the Open-ZB open-source toolset.

Recent scientific and technological advancements within the ART-WiSe framework have been demonstrating the feasibility and effectiveness of the IEEE 802.15.4/ZigBee protocols as federating communication technologies for Wireless Sensor Networks, particularly for applications with stringent QoS requirements, such in Cyber-Physical Systems. Fortunately, our vision on using standard COTS technologies in large-scale embedded computing applications has been and is being recognized by the academic and industrial communities at large.

Thank you all for your trust and contribution, and stay tuned for upcoming upgrades of the toolset. Ongoing migration of the Open-ZB protocol stack to TinyOS 2.0 (within the collaboration with the TinyOS Network Protocol Working Group) and to Contiki (within the collaboration with SICS - Swedish Institute for Computer Science) will hopefully see the light soon.
